SINGLET'REE.

SPECIFICATION forming part of Letters Patent No. 373,025, dated. November 8, 1887.

Application filed February 19, 1887. Serial No. 228,208. (No model.)

To aZZ whom, it may concern.-

Be it known that I, OSCAR FITZALLEN LOWE, of Hampton, in the county of Franklin and State of Iowa, have invented a new and useful Improvement in Singletrees, of which the following is a specification.

My invention is an improvement in singletrees, and relates particularly to the construction of the clips, whereby the same will be efficient in use, and the portion thereof subjected to wear may be readily replaced when worn or otherwise useless.

In the drawings, Figure 1 is a perspective view of a portionof a singletree provided with my improvement. Fig. 2 is a detail view illustrating the center clip, the parts thereof being detached, and Fig. 3 shows one of the end clips in detail.

The invention consists in certain features of construction and novel combinations of parts, as will be described, and pointed out in the claims.

The end clip, A, has a body or thimble, A, having one side open and provided with lugs a a thereat, the same having perforations b for the pivotbolt I3. The hook proper, C, is formed at its rear end with a lug or portion, a, fitted between the lugs a, and havingan opening for the passage of bolt B, whereby it is pivotally supported. This portion is eX- tended at D outside of the lugs, and has such extension provided with a projection, d, which 'sion D, as shown.

. the hook and hold the same normally closed.

The point of the hook is made longer than the rear end of same, and in the closed position of e the hook projects in rear thereof, such construction serving to reduce the probability of the trace becoming accidentally detached. To

further such end I enlarge the point of the hook-it may be by bending it inward at F,

as shown, and such end is seated in a socket or cavity, f, formed in the singletree, thus practically closing the hook.

It will be seen that the hook will secure the trace whether tight or slack, and that the hook or part subjected to the greatest wear may be readily replaced when worn.

The body G is formed of a plate of metal of suitable thickness, bent into thimble form at g to fiton the singletree, and provided at its edges with the ears H, having the lugs h at their ends, being rounded out between said lugs in order to supplement or increase the size of theopening in the eye. The eye I is formed of a bar of metal bent into arch form and having its ends tenoned at J to fit between the ears H, and having openingsj for the bolts K, which are applied as shown, and are secured by the nuts 7c.

It will be seen that the body may be applied to the singletree, and the eye be secured to the body. Then when the eye becomes worn it may be removed and another substituted in its stead, the body being suited to receive another eye, as will be understood.

It will be seen that the body or clip proper can be placed on the singletree without burning, and thereby injuring the said tree, and the services of a blacksmith or other skilled person will not be requisite to the proper attachment thereof. The eye, the least expensive part, receives the wear, while the main and most expensive part is not materially injured by use, and will wear out a number of eyes, whereas in the common form of clip when the eye is worn out the clip is useless.

My form of center clip also brings the sin-.

gletree nearer to the evener or doubletree, thus bringing the team nearer to the load or work than can be effected by the common form of clip..

The shoulders of the eye I next the tenons thereof are rounded at t, and the ends of the lugs are similarly rounded, so that by removing one b'olt K the eye may be swung on the other to properly receive a chain, the end of which is provided with a hook or other construction too large to pass through the eye.

Having thus described my invention, what I claim as new is 1. The combination, in a singletree, of the body or thimble, the hook pivoted thereto and having an extension, D, and a projection, d, on said extension D, snbstantiall y as set forth.

2. The combination of the singletree, the two pairs of lugs h 71, secured to the singletree and separated, as described, the eye having its ends perforated and fitted between the lugs 71, and the bolts for connecting the ends of the eye with the lugs 71, all being arranged substantially as described, whereby one of the said bolts may be removed and the eye be turned on the other as a pivot, substantially as set forth.

3. The combination of the thiinble having lugs, the hook pivoted between the lugs, and I5 having the extension D, provided with projection d,and the spring,substantially as set forth.

4. A clip having a clip proper or body provided with ears, and having an eye provided with tenons fitted between said ears, and the 20 connections, substantially as set forth.
